Hi, thank you for your help. It is working now. Problem was that I had to use just css class and not identificator. I also edited code a little, because there was space under main menu in category "rezervace".
/* Here you can include your override CSS styles */
body > .gkReservationForm { display: none; }
/* Header menu-visible */
#gkHeader.menu-visible {
padding-top: 30px;
}
/* Blog */
.bigtitle .header > a, .bigtitle .header > span, .bigtitle > header > a, .bigtitle > header > h1 > span {
padding: 10px 20px;
Is it all right?
Thanks
